Dehydropolycondensation Aminophenols under the Catalytic Action of Metallic Chelate Compounds () Reactions of the Isomers, Reaction Mechanisms, and the Structures of the Oligomers

[摘要] In the oligomerization of p-aminophenol by the catalytic action of Fe-EDTA complex in the aqueous medium, the mixed complex intermediate, Fe-EDTA-M type, is considered to be formed, from which active radicals of the monomer are produced. In this system, polymerization is presumed to proceed as follows: Free radical formation ¡æ Coupling ¡æ Activation ¡æ Coupling, and so on. In this study, the form of the monomer and coordination state in the mixed complex, the catalytic action of Fe-EDTA the complex, the reaction mechanism, and the structure of the oligomers are discussed.
